چکیده
We present a detailed analysis of resonance contributions in the context of higher twist effects in the moments of the proton spin structure function g 1. For each of these moments, it is found that there exists a characteristic Q 2 region in which (perturbative) higher twist corrections coexist with (non-perturbative) resonance contribution of comparable magnitude.

Resonances and higher twist in polarized lepton-nucleon scattering∗

Exciting and even unexpected results have been presented in the sessions about “polarized lepton nucleon scattering”, at the DIS 99 workshop. Most striking are the presentations of the flavor decomposition of the quark polarization, the first direct observation of a positive gluon polarization in the nucleon and the observation of a double-spin asymmetry in diffractive ρ production. First resul...

The single spin asymmetries for a longitudinally polarized lepton beam or a longitudinally polarized nucleon target in semi-inclusive deep-inelastic scattering are twist-3 observables. We study these asymmetries in a simple diquark spectator model of the nucleon. Analogous to the case of transverse target polarization, non-vanishing asymmetries are generated by gluon exchange between the struck...
متن کاملAzimuthal and single spin asymmetry in deep-inelastic lepton-nucleon scattering
We derive a general framework for describing semi-inclusive deep-inelastic lepton-nucleon scattering in terms of the unintegrated parton distributions and other higher twist parton correlations. Such a framework provides a consistent approach to the calculation of inclusive and semi-inclusive cross sections including higher twist effects. As an example, we calculate the azimuthal asymmetries to...

We investigate the possibility to measure the nonforward gluon distribution function by means of diffractively produced π+π− and K+K− pairs in polarized lepton nucleon scattering. The resulting cross sections are sizable and are dominated by the gluonic contribution. We find large spin asymmetries, both for π+π− and for K+K− pairs. PACS. 12.38.-t, 13.60.-r, 13.60.Le
